# 📋 Windows: Create a .p12 / .pfx certificate from a .p7b file

This article is a step-by-step guide for administrators on how to convert an SSL certificate from .p7b format to the required .pfx or .p12 format using the Windows Certificate Manager.

## 📋 Windows: Create a .p12 / .pfx certificate from a .p7b file

To provide an SSL certificate to FTAPI Support, you need it in `.pfx` or `.p12` format. If you have received your certificate in `.p7b` format, you can combine it with the private key and export it using the Windows Certificate Manager.

## Step-by-step guide

1.  **Open Certificate Manager:** Open the Windows Certificate Manager via the Run dialog (Windows key + R) and the command `certmgr.msc`.
2.  **Import .p7b file:** Import the received `.p7b` file into the Certificate Manager.
3.  **Check private key:** Ensure that the private key associated with the certificate is present and linked in the system.
4.  **Export certificate:** Right-click on the certificate and select "All Tasks" $ ightarrow$ "Export...".
5.  **Select format:** Follow the export wizard and select **"Personal Information Exchange - PKCS #12 (.PFX)"** as the format.
6.  **Export private key:** In the export wizard, enable the option **"Yes, export the private key"**. This is mandatory.

## Important note on the password

You will be prompted during the process to set an export password for the `.pfx` file. This password is essential for using the file later.

> **Ensure that you save the password securely after the export and provide it to FTAPI Support along with the .pfx file (please only via a secure channel, e.g., a SubmitBox).**
